Don't invite Shia LaBeouf to your next party

There are varying accounts of exactly what happened Friday night, but both make it clear that Shia was up to no good.

Page Six has this: "Shia LaBeouf was escorted out of the LA opening of The Box nightclub by security Friday night after a confrontation with a pal of shock rocker Marilyn Manson. The “Transformers” star “exchanged terse words with a friend of Manson’s, who lunged over the table at Shia, and Shia lunged back. Security stepped in quickly and broke it up before any punches were thrown,” a source at the party hosted by Belvedere Red told us, adding, “Two security guards led Shia out holding his hands behind his head. His girlfriend, Karolyn Pho, was clearly upset and ran down the stairs after them. Outside, he fell onto a barricade. Swearing, he picked himself up and ran off.” Despite numerous witnesses at the party, also attended by Jon Hamm, Lindsay Lohan and Chelsea Handler, Shia’s rep said: “[He] actually left the club early as planned ... he went to see one of the bands performing in the showcase and left after they finished ... exiting through a crowded room was apparently misinterpreted. No altercation occurred.”

Life & Style has this: Onlookers at an LA party were concerned for Shia LaBeouf last night after the actor exhibited some very strange behavior. The Transformers star had what one witness tells Life & Style seemed to be "a public meltdown," spitting water over his date and rocker Marilyn Manson before charging through the crowd to the exit At the Aug. 26 (BELVEDERE) RED at The Box party, the witness tells Life & Style, "Shia picked up a water bottle and shot a mouthful of water all over his seated date's legs. "Then he put more water in his mouth and started spitting it all over his tablemates, including Marilyn Manson. He seemed wasted." But according to the witness, neither his date, his friends nor Marilyn could calm Shia down - even after Marilyn offered a fist bump, as if to say everything was fine. "People started taking their seats in front of the stage at the event, but all of a sudden Shia started shouting at his date and getting visibly angry," the eyewitness tells Life & Style. Then he headed for the door. "He lunged through the very thick seated crowd, and the crowd pleaded with him and encouraged him to sit down. They tried to hold him back -- but he kept struggling through." And the audience at the event got more than just the show it came to see. "Shia had to climb over people and tear himself out of the grasp of various strangers who were trying to keep him from going crazy," the eyewitness says. "His date panicked and ran out after him. Marilyn looked shocked and annoyed but stayed seated. Shia and the girl did not return." "It was so insane -- he just had a total meltdown right in front of everyone," the eyewitness tells Life & Style. "It was completely out of control. He was so angry and physical. He was determined to get out of there."

UPDATE: "Shia actually left early as planned," Shia's rep tells Life & Style. "He went to see one of the bands performing in the showcase and left after they finished. Exiting through a crowded room was apparently misinterpreted. No altercation occurred."
